The _ is a metric unit of volume


For ease of understanding, scientists report measurements using the __ system

SI Unit

Whether applications of science to everyday life are considered good, bad, right, or wrong comes under the category of _


A brain scan is an example of __


The theme that reflects the idea that there has been a gradual change in the characteristics of species over time is __


Living things adjust to a stimulus by a reaction called a


Living things change during lives through

growth and development

All living things __ to make more living things


The study of standards for what is right and what is wrong is called


The information gathered from experiments is called

the data

A scientific explanation of known facts arrived at through repeated testing over time is a


To use data to support a particular point of view

This is NOT a goal of science

Information gathered from observing a plant that grows 3 cm over a two-week period results in


using a feeling about what should occur

This is NOT a way scientists generate hypotheses

Scientific hypotheses must be proposed in a way that

enables them to be tested

The ability to reproduce results is an important port of any


The work of scientists begins with

careful observations

A controlled experiment allows the scientist to isolate and test

a single variable

Scientists publish the details of important experiments so that

their work can be repeated, their experimental procedures can be reviewed, and so that others can try to reproduce the results

The process by which organisms keep their internal conditions fairly constant is called


In the metric system, the basic unit of length is the


the gradual change in the characteristics of a species over time


the living and nonliving factors in an organism's surroundings


Any structure, behavior, or internal process that enables an organism to better survive in an environment


An organism's tendency to maintain a stable internal environment


the series of changes that an organism undergoes during its lifetime


the process whereby an organism produces more of its own kind


its flow through ecosystems determines how organisms interact and powers all life processes


a variety of structural and behavioral adaptations help organisms relate their internal environment


organisms depend on internal and external systems that interact in complex ways to help them perform their life functions

systems and interactions

Over time, gradual changes in structures, behaviors, and internal processes of organisms result in diversity of species


although different organisms interact within ecosystems to form a stable system, all living things share the same characteristics of life

unity within diversity

biology is a continuous search for information about the natural world

nature of science
